ABSTRACT:
A steel laminate gasket of the invention is installed in an internal combustion engine having at least one fluid hole and a plurality of bolt holes therein. The gasket basically comprises first and second plates for constituting the steel laminate gasket, and includes holes corresponding to the fluid hole and the bolt holes. A sealing device is formed around the fluid hole for sealing therearound when the gasket is tightened. At least one seal protecting member is integrally formed with the second plate. The seal protecting member extends from the second plate and is turned near the bolt hole to pile together with the first and second plates adjacent the sealing device. When the gasket is tightened, a part of the tightening pressure applied by the bolts is supported by the seal protecting member to thereby provide moderate tightening pressure to the sealing device.
